Chowder/Funny

In "Shopping Spree", Mung, Chowder and Shnitzel go to a mall and spend all of the money in Truffle's money box while she is ill. Not only can they not afford all the stuff they bought, but they can't afford the animation and are consequently reduced to their respective voice actors: Dwight Schultz, Nicky Jones, John DiMaggio and Tara Strong. So what do they do? They have a car wash. [1]
Turn on captions while "The Blackout" is on and pay attention to what the weirdos say.

Large Female Weirdo: I like pirates and movies and movies about pirates.

- The big-headed weirdo looks like Bill from King of the Hill.
In "The Party Cruise", Mung tries to excite Chowder on a fishing trip by telling him a story:

Mung: Did I ever tell you of the time I went on my thousand-day fishing trip?
Chowder: How many days?
Mung: A thousand.
Chowder: OH GOSH.

"Look Mung, I'm an Arborian!"
A lot of stuff involving the Marzipan PD.
The tail end of the bluenana episode was pretty hilarious...

Baby Bluenana: (Cough) Mother..? Is that... you? Take me away from theses horrible people!
The mother then proceeds to call Panini and Chowder monsters and runs away crying as everyone still has a WTF? face on them.

"Pepper spray? That sounds delicious...(gets sprayed in the face) I WAS WRONG! I WAS HORRIBLY HORRIBLY WRONG!"
This exchange from the Marmelade episode:

Panini: Chowder, get over here.
Chowder: But...can't I have more than one friend who's a girl?
Panini: No. Don't test me, Chowder.
Chowder: ...What flavor lip gloss are you wearing?
Panini: Smackdown. Now get over here.
Chowder: Uh, I think I'd rather stay with Strawbarbleberry...

"Hey Mung! I'm gonna make you pee your pants!"
Mung on the Meaches: "They broke every bone in my body! They even ate my hair!"
After Mung gives up trying to build a schmingerbread house he says "Knishmas is ruined, and it's all Schnitzel's fault."
The "At Your Service" episode, especially the part where Endive tells Panini to "put on some Celine" as Mung and Chowder rid Endive's pool of bugs.
Mung's failed attempt to save Truffles during a flood.

"This isn't supposed to sink! It's MADE OUT OF FISH!"

When Panini makes Chowder hold her hand in "Banned from the Stand". Panini's reaction seals it:

Chowder: IT-- BURRRRNS!!!
Panini: Let's go. Look everyone, we're holding hands! *~n_n~*

When Chowder is trying to get Mung Dal to taste what he made.

Chowder: Please?
Mung Dal: No, Chowder.
Chowder (somehow now a woman): (seducingly) Pretty please?

Mung Dal: WHAT THE!?

In the episode where Endive thinks she killed Mung, she imagines herself in the West Pole. Her line truly captures what one would think if they ever went to such a place.
"Tofu Town":

It was back when Tofu Town looked very much like 1960's Tokyo.

His greatest enemies were the Anime Hair wearing Teriyaki Triads!

- The leader of the Teriyaki Triads speaks in a hysterically bad dub voice.
The beginning of "Weekend at Schnitzel's", where after several seconds of them doing nothing Chowder blurts out "This is boring, you're boring, life's boring, and this episode is boring!".
